Share access requests (iOS 26) via CloudKit Web Services / CloudKit JS?

iOS/macOS 26 added share access requests: CKShare.allowsAccessRequests, CKShare.requesters, CKShareRequestAccessOperation, and deny/block requesters on CKShare. My app uses this flow on iOS, macOS and watchOS:

  • The owner sets allowsAccessRequests = true and shows the share URL as a QR code.
  • The joiner runs CKShareRequestAccessOperation for that URL.
  • The owner reads requesters and approves (adds a participant), denies or blocks.

I'd like to do part of this from the web. I can't find anything about access requests in the CloudKit Web Services reference or the CloudKit JS docs.

  1. Is there a supported way to read/set allowsAccessRequests, submit an access request, or list/approve/deny/block requesters through Web Services or CloudKit JS?
  2. If not, is there a recommended workaround?

I've filed this as a suggestion: FB25372887
